SPECIFICATION forming part of Letters Patent No. 417,465, dated December1'7, 1889.

Application filed May 19, 1888. Serial No. 274,369. (No model.)

To all whom it may concern.-

Be it known that I, JOSEPH HENDERSON BEHEE, of Leavenworth, in thecounty of Leavenworth and State of Kansas, have invented a new andImproved Furnace, of which the following is a full, clear, and exactdescription. e The object of this invention is to increase theradiating-surface of the furnace, and at the same time to so arrange theseveral partsof the furnace that the draft may be regulated to suit therequirements of the weather.

A further object of the invention is to so arrange the several fluesthat they may be quickly and readily cleaned, such cleaning ofthe uesbeing absolutely essential where soft coal is burned.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar figures of reference indicatecorresponding parts in all the views.

Figure 1 is a face view of my improved' furnace. Fig. 2 is across-sectional view of the same, the view being taken 0n line w ofFig. 1. Fig. 3 is a sectional plan view on line y y of Fig. 2,partsbeing broken away. Fig. 4 is a sectional plan view on line .e z ofFig.

2. Fig. 5 is a front View of the furnace, thev front wall being removedand the flues being A shown in partial section; and Fig. 6 is aviewtaken in the direction of the arrow a, Fig. 5, the front Wall and thelower flue-walls being shown in section.

In the drawings above referred to, lO represents the fire-pot; 11, thegrate; 12, the receiving-chute, which is normally closed by a door 13,the receiving-chute extending outward through the front wall 14., asshown.

From the top of the fire-pot there leads a pipe 16, which joins thesmoke-stack 18, and in this pipe 16 there is mounted a damper 17, thestem of which extends outward through the masonry in which the furnaceis set, and is there provided with a handle 2, the arrangement beingsuch that if the damper be drawn outward the draft will be direct fromthe fire-pot -to the smoke-stack, and this damper should always be drawnout when a fresh fire is made, or when it is desired to kindle up a firethat has become almost extinguished.

After the fire has been lighted the damper 17 is closed, and then theproducts of combustion pass through two pipes 2O downward 55 to upperflues 21, the pipes 2O entering the iiues 21 at their forward ends. Fromthe flues 21 the products of combustion enter flues 22 through openings3, and from the lues 22 the products pass on through aper- 6o tures 4into a central return-flue 24, which is in direct communication with thestack 18. In this way it will be seen that a great expanse of metal isheated, and the cold air, which is delivered from the chamber about there-pot in the usual manner and enters through a Hue 26, must necessarilypass over this heated surface. At times a less amount of heating-surfacewould be required, and to cut off a portion of the sur- 7o face and atthe same time to increase the draft of the furnace I provide dampers 5,which are hinged in position, so that they may be moved to close theapertures 3 and open a way so that the products of combustion will passthrough other apertures 6, and thence directly through the smoke-stack.

The flues 21 and 22 are provided with doors 30, (see Fig. 1,) whichdoors may be swung open when it is desired to clean out the 8o fines, asimilar door 31 being arranged in connection with the centralreturn-fine 24. Just above this central return-due 24. there is anash-chamber 32.

Having thus fully described my invention, I claim as new and desire t0secure by Letters Patentv 1. A furnace consisting in a fire-pot, anash-pit, an outlet-pipe 16, provided4 with a damper, a vertical stack1S, into which said 9o pipe discharges, upper and lower horizontal lines21 22 at opposite sides of the ash-pit communicating at their rear ends,and a central horizontal iiue 24' under the ash-pit, and with theforward end of which the lower flues 22 communicate, said central flueopening at its rear end into the lower end of the stack, substantiallyas set forth.

2. The combination, in a furnace, with the fire-pot having iues leadingdownward from roo the upper portion thereof, opposite horizoning fromthe upper end of the furnace into tal flues into which the rst-named uesthe stack and provided with a damper, subro discharge, and a centralflue communicating stantially as set forth.
